Mallaranny—sometimes spelt as Malaranny, Mullaranny, Mullranny or Mulranny—is a seaside village on the isthmus between Clew Bay and Blacksod Bay in County Mayo, Ireland. Mallaranny is the home of colourful giant fuchsias and exotic plants. This plant life is celebrated each summer during the Mallaranny MediterraneanHeatherFestival. Mulranny has been cited as a possible source of the ancient Gallowglass MacNevin family, who originally emigrated to Scotland in the mid 10th Century. The Nevin Coat of Arms has a Fern as a main symbol.

Mallaranny has long sandy blue flag beaches and a relatively mild climate. The Corraun Peninsula, which contains three mountain peaks, is situated across Clew Bay.
